Package: Invicti AppSec Core (on-demand)

Slack Integration

Slack is a cloud-based team messaging and collaboration platform widely used for real-time communication within engineering and security teams. The Invicti AppSec integration with Slack enables security teams to receive automated notifications about vulnerability events — such as new findings, scan completions, or status changes — directly in Slack channels.

Purpose in Invicti AppSec

Slack is used in Invicti AppSec as an Notification Tool — enabling automated security event notifications to be delivered to Slack channels or direct messages.

Use Case	Description
Vulnerability notifications	Receive alerts in a Slack channel when new vulnerabilities are discovered or severity thresholds are reached
Scan completion alerts	Get notified in Slack when a security scan finishes
Status change updates	Receive updates when vulnerability statuses change (e.g., opened, resolved, re-opened)
Channel-based routing	Route notifications to specific public or private channels relevant to each project or team

Where It Is Used

Page	Navigation Path	Purpose
Integrations — Notification Tools	Integrations › Notification Tools	Admin activation and global configuration
Project Settings	Project › Settings › Alerts	Link Slack to a specific project for project-level notifications

Prerequisites

Before activating the integration, gather the following from your Slack workspace:

Field	Description	Required
Token	A Slack Bot Token (OAuth token) with the required scopes to post messages to channels	Yes

How to Obtain the Bot Token (on the Slack Side)

1. Go to https://api.slack.com/apps and click Create New App.
2. Choose From scratch, give the app a name (e.g., Invicti AppSec), and select your workspace.
3. In the app settings, go to OAuth & Permissions.
4. Under Bot Token Scopes, add the following scopes:
   • chat:write — to post messages to channels
   • channels:read — to list public channels (required if Include Public Channels is enabled)
   • groups:read — to list private channels (optional)
5. Click Install to Workspace and authorize the app.
6. Copy the Bot User OAuth Token (starts with xoxb-). This is the token to use in Invicti AppSec.
7. Invite the app to the Slack channel(s) where notifications should be sent by running /invite @YourAppName in the channel.

Activation Steps

Step 1: Navigate to Integrations

From the left sidebar, click Integrations.

Step 2: Open the Notification Tools Tab

Field	Description	Required
Token	Slack Bot User OAuth Token (starts with xoxb-)	Yes

Step 5: Test the Connection

Click Test Connection. A green "Connection successful" message confirms that Invicti AppSec can authenticate with Slack using the provided token.

Step 6: (Optional) Configure Advanced Settings

Click Save within the Advanced Settings section to apply changes.

Step 7: Save

Click Save to complete the activation.

Troubleshooting

Issue	Resolution
Connection failed	Verify the Bot Token is valid and starts with xoxb-. Ensure slack.com is reachable from the Invicti AppSec network.
Invalid token	The token may be expired or revoked. Reinstall the Slack app in your workspace to generate a new token.
No channels listed	Ensure the bot is invited to at least one channel using /invite @YourAppName. Enable Include Public Channels in Advanced Settings to see public channels in the dropdown.
Missing scope	If certain channels are not accessible, check that channels:read and groups:read scopes are added to the Slack app.
Bot not posting messages	The bot must be a member of the target channel. Use /invite @YourAppName in the Slack channel to add it.
